Light from the sun reaches the earth in 8.3 minutes. the velocity is 3.00 x 10^8 m/s. how far is earth from the sun? i know how to get to d = (3 x 10^8 m/s)(498 sec). i just don't know how to get from there to the answer being 1.5 x 10^11 m.

An object moves from position +34m to the position -15m in 15 seconds. what is the total displacement? what is the total velocity?

The speed of light can be used to measure the
